What can't stay overnight is stem and leaf vegetables. The nitrate content of stem and leaf vegetables is the highest, melon vegetables are slightly lower, and rhizomes and cauliflowers are in the middle. Therefore, if you buy a lot of vegetables at the same time, you should eat leafy vegetables, such as Chinese cabbage and spinach. If you are going to cook more vegetables and eat them hot the next day, you should try to make fewer stem and leaf vegetables and choose melon vegetables.

Overnight foods that should not be eaten include fish, seafood, green leafy vegetables, cold salad and so on.

Seafood such as crabs, fish and shrimps will produce protein degradation products overnight, which will damage the liver and kidney function. If you really buy too much, you can pack raw seafood in fresh-keeping bags or boxes, freeze it in the refrigerator and cook it next time.

Extended data

Overnight dishes are harmful.

Overnight dishes not only lose nutrients seriously, but also produce harmful substances. I want to remind everyone that vegetables and seafood should not be eaten overnight, and meat must be steamed and cooked thoroughly to prevent food from being stored for a long time, spoiling and deteriorating, leading to food poisoning.

Because some green leafy vegetables contain more nitrates, if they are left for too long after cooking, nitrates will be reduced to nitrite under the decomposition of bacteria, which is carcinogenic and cannot be removed by heating.
